THE SEA-DWELLER 1967

1967 saw the launch of the Oyster Perpetual Sea-Dweller, waterproof to a depth of 610 metres. To meet the needs of professional deep-sea divers, the case was equipped with a helium escape valve so that, during long decompression phases in hyperbaric chambers, the helium from the gas mixtures used could be released without risking damage to the watch.
